This molecule is linked to fibrosis and has been seen in other lung diseases. Features of CD8+ T cell populations enriched in patients with restrictive lung disease. A major study from the University of Virginia finds that specific immune changes in Long COVID patients reveal the severity of their lung damageoffering new hope for targeted treatments. However, fibrotic lung damagescarring of lung tissuewas still present in many even two years after their infection. For example, people with restrictive lung diseasea condition where the lungs cannot expand fullyshowed two main immune patterns. These differences helped researchers understand how complex Long COVID really is. Interestingly, 41% of patients improved over time, shifting into a group with milder lung problems. In those with more severe lung scarring, other immune markers appeared. (CREDIT: Nature Immunology)Another surprise was that some patients had severe fatigue and breathing issues but normal lung function.
